What's New in Oxygen Publishing Engine 27
November 27, 2024
Oxygen Publishing Engine version 27.0 encompasses the improvements and additions implemented in Oxygen XML WebHelp and Oxygen PDF Chemistry. This version adds some additional customization options for producing WebHelp and PDF output
There are changes in:
WebHelp Output
Disable Zoom for Images
It is now possible to disable the WebHelp zoom functionality for particular
          images. You can flag the images that should not have zoom functionality by using the
            no-zoom value for the 
@outputclass attribute on the
          particular images.Open Custom Logo URL in a New Tab
You can control whether clicking the URL for a custom WebHelp logo will open it
          in the same tab or in a new tab. This can be configured using the new
            
webhelp.logo.image.target.url.new.tab parameter. By default, the link
          is opened in the same tab as the WebHelp output.Display Certain Elements as Tabs
It is possible to display certain elements as tabs by using the
            
outputclass="wh-tabbed" attribute. This works for lists
            (<ol>, <ul>), definition lists
            (<dl>), and choice table (<choicetable>)
          elements.Open WebHelp and PDF Produced by DITA OT Project

          application.
